What is the half-life of levodopa?

Dizziness, lightheadedness, nausea, vomiting, loss of appetite, trouble sleeping, unusual dreams, or headache may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. This medication may cause saliva, urine, or sweat to turn a dark color.
What is the mechanism of action of levodopa?
Levodopa is a prodrug that is converted to dopamine by DOPA decarboxylase and can cross the blood-brain barrier. When in the brain, levodopa is decarboxylated to dopamine and stimulates the dopaminergic receptors, thereby compensating for the depleted supply of endogenous dopamine seen in Parkinson’s disease.
Why does levodopa become less effective?
The dopamine level in your brain gradually declines, which makes it harder for each dose of levodopa to prevent symptoms re-emerging. Doses of levodopa are effective for a shorter time. When this happens, most people start to experience fluctuations in symptom control throughout the day.
What happens if you stop taking levodopa?

What foods decrease dopamine?
Diets high in sugar and saturated fats can suppress dopamine, and a lack of protein in a person’s diet could mean they do not have enough l-tyrosine, which is an amino acid that helps to build dopamine in the body.
